Overview

Novel strategy fabricates a graphene oxide membrane for lithium recovery from spent battery leachate, suggesting environmental benefits.

Key Points

  • To develop a method for recovering lithium from cathode leachate using membranes made from graphite.
  • Fabrication of a graphene oxide-polyethyleneimine (GO-PEI) membrane from spent graphite.
  • Use of the membrane for selective lithium extraction from cathode leachate.
  • Evaluation of membrane performance and lithium recovery efficiency.
  • The GO-PEI membrane effectively recovers lithium from the leachate.
  • The process demonstrates environmental sustainability by utilizing spent battery materials.
